Patent DE-3341286-A1 (DE)
Title: Inversely thermostatically acting actuator for heater valves
Inventor: LUIKEN ANDREAS
IPC: F16K31/68
Filed: 1983-11-15
Abstract: If a heater valve is regulated via a plurality of thermostatically active actuators, and if one or more of the latter acts inversely, the desired temperature value at the temperature sensor of an inversely thermostatically active actuator is matched in the case of a slow temperature drop, for example  DELTA T/t < 1 DEG K per min, to the temperature at the temperature sensor. If the temperature at the temperature sensor drops sufficiently rapidly, for example  DELTA T/t > 2 DEG K per sec, this temperature sensor effects closure of the heater valve via an inversely thermostatically active actuator, irrespective of the absolute temperature at the temperature sensor. The inversely thermostatically active actuator does not need to be controlled. Closure of the heater valve is performed without delay as soon as cool external air first flows into the heated room. No extraneous energy is required for regulation.
Patent DE-3343961-A1 (DE)
Title: Method of producing piles or pile-like bodies
Inventor: BERG JOACHIM DIPL ING
IPC: E02D9/00
Filed: 1983-12-06
Abstract: A method of producing piles or pile-like bodies of defined length is specified, concrete or another suitable filling agent being placed into a prepared ground opening or the like which in its axial extent is greater than the length of the finished pile. After the fresh concrete or the like is poured into a prepared ground opening, a mechanical means of variable geometric configuration is sunk parallel to the longitudinal axis of the ground opening. Here, the sinking depth approximately corresponds to the level of the top end of the finished pile. The sinking is effected for the purpose of separating that part of the filling agent which is located above the finished pile. The separation of this part from the finished pile is done by the action of a force (P) approximately perpendicular to the longitudinal axis of the pile.

Title: Inductor for transmitting low-frequency current or direct current, and for blocking high-frequency current
Inventor: ELLE KLAUS-PETER ING GRAD
IPC: H01F37/00
Filed: 1983-12-07
Abstract: An inductor is proposed which is used for transmitting low-frequency current or direct current, and for blocking high-frequency current. The inductor (30) has three inductor segments (31, 32, 33) which are arranged parallel to the axis. Each inductor segment has a core (34, 35, 36) and in each case one winding. However, if necessary, all three cores may also have a common winding (37). The cores of the two outer inductor segments (31, 33) have a core which is as highly permeable as possible. The core (36) of the central inductor segment (32) is intended to have a high saturation magnetisation and to have a permeability which is low in comparison with the other cores. In each case one insulating material disc (38, 39) is located between the cores which are arranged parallel to the axis. <IMAGE>

Title: Process for regulating the temperature in a gas-fired water boiler, especially a heating boiler
Inventor: GELEWSKI HUBERT
IPC: F23N5/02
Filed: 1983-12-22
Abstract: Process for regulating the temperature of a gas-fired heating boiler, in which for a predetermined time a sufficiently proportioned excess of ignition gas for assured ignition is supplied to the burner (12) on switching on, both in a continuous control range and also in a two-point control range. After a control switch-off in the two-point control range, the start signal of the controller (22) turning the burner (12) on again is released by a voltage which simulates a deviation from the reference value higher than the actual deviation being superposed on the actual-value voltage signal emitted by a temperature sensor (24). The temperature drop in the control switch-off pauses, which was hitherto set by the required starting gas quantity within the proportional range of a heating appliance with constant power control, can thus be reduced as desired. <IMAGE>

Title: Cooling bed ventilation system
Inventor: PECHAU GERHARD DR ING
IPC: B21B43/00
Filed: 1983-12-24
Abstract: The invention relates to a cooling bed ventilation system in light-section rolling mills for the accelerated cooling of the rolled material cut to cooling-bed lengths. The cooling beds concerned are the known cooling beds in a rolling shop constructed in storeys. The aim of the invention is to increase the cooling rate by increased circulation of cooling air around the rolled material without increased constructional outlay on the cooling bed. It is the object of the invention to modify the cooling-bed foundations and the cooling-bed shop in such a way that the flow resistances to the cooling air right through from the air inlet to the shop to the air outlet on the roof of the shop are low and thus that improved cooling of the rolled material is achieved by natural convection. The object is achieved by the fact that, to give optimum matching of the coefficients of flow resistance, the side walls 8 of the shop have, in the cooling-bed region, air inlet openings 9' and 10' designed to give optimum flow and the air outlet openings 19 are provided in the upper part of the side walls 8 in addition to the known air outlet openings 18 in the roof region in order to enlarge the total area for air discharge. <IMAGE>

Patent DE-3403427-A1 (DE)
Inventor: ANDRADE JUAN DIPL CHEM DR
IPC: C07C45/51
Filed: 1984-02-01
Abstract: The preparation of 1,4-butandial (succindialdehyde) is obtained using acrolein. The acrolein is first converted with an alkanol into 3,3-dialkoxy-1-propene and this is then hydroformylated in the presence of hydridotristriphenylphosphine-rhodiumcarbonyl mixed with triphenylphosphine or triphenylphosphite as the catalyst. The thereby obtained 4,4-dialkoxy-butanal is removed from the hydroformylation product by means of distillation and is then hydrolyzed to 1,4-butandial.

Title: Method and devices for increasing the complex efficiency of vehicles
Inventor: RAEHMER HANS
IPC: F02B61/04
Filed: 1984-02-25
Abstract: In the context of further development of the method claimed in the basic patent, the scope of the invention was extended in that the emphasis focuses on the principle of a thermal increase of the thrust efficiency, that is to say that the increase of the complex efficiency of the vehicle propulsion can also be obtained with means other than the waste heat of an engine. Similarly external heat sources may in certain cases also be appropriate for the heating of the propellant and thus for increasing the energy content. Favourable design details were claimed for the main technical problem of the process, a functional hot gas propelling nozzle (1). <IMAGE>

Patent DE-3410868-A1 (DE)
Title: Re-usable, positively-locking nut lock
Inventor: LE THANH-SON DIPL ING
IPC: F16C35/063
Filed: 1984-03-21
Abstract: In the case of this positively-locking nut lock principle, the formation of the positive lock between the nut and the screw takes place via a lock part which is integrated on the nut. The locking arms (which are provided with blocking elements) of the lock part are radially pressed together by means of a tool or an auxiliary nut, so that the hardened tips of the blocking elements penetrate in a positively-locking manner, and independently of the nut position, into the material of the screw, without play. If the nut and the locking part are elastically connected to one another in a positively-locking or force-fitting manner via a spring element, then in the locked state, the nut is continuously subjected to a restoring torque and, possibly, to an axial restoring force of the stressed spring element in an attracting manner and, possibly, in a pressing-on manner, so that the screw union is also still locked against seating. The screw union is detachable again when the positive lock between the screw and the lock part has been removed by pressing the locking arms apart. The nut, together with the lock part and the screw, are re-usable, and the positively-locking locking process is reproducible and can be mechanised.

Title: Vehicle brake system with antilock device
IPC: B60T8/44
Filed: 1984-04-10
Abstract: The vehicle brake system (2) has two closed brake circuits (I, II) with wheel brakes, a tandem master cylinder (3) with main pistons (16, 18), which are displaceable by means of a pedal (9) by way of a brake booster (6), and an antilock device. The latter comprises an adjusting cylinder (4), an adjusting piston (5), a pressure supply (11), a pressure medium reservoir (25), a 3/2-way valve (37), which in its basic position connects the adjusting cylinder (4) to the pressure medium reservoir (25) and in the event of antilock connects the adjusting cylinder (4) to the pressure supply (11) in order to reduce brake pressures, and 2/2-way valves (33, 34, 35, 36) built into the brake circuits (I, II), which constitute pressure maintaining valves. If a vehicle wheel is overbraked, those 2/2-way valves which are not assigned to a wheel brake of the overbraked wheel, are shifted into their pressure maintaining position. In addition, the 3/2-way valve (37) connects the pressure supply (11) to the adjusting cylinder (4), so that the adjusting piston (5) is pressed against the brake booster (6). As a result, the main piston (18) moves in the direction of its starting position, thereby producing a reduction of the brake pressure in the desired way. Owing to its closed brake circuits (I, II) the vehicle brake system (2) is inexpensive and has a very high operating reliability. <IMAGE>
Patent DE-3417213-A1 (DE)
Title: Method of storing information and device for verifying the validity of the method
Inventor: JAEGER ROBERT DR ING
IPC: G11C11/20
Filed: 1984-05-10
Abstract: While with non-linear resistance characteristics storage elements for storing information in the time domain can be realised, with non-linear reactance characteristics storage elements can be constructed in the frequency domain. For this, two examples are described in the method applied for, both being based on hysteresis effects (bistable ranges) of the complex reflectance factor. The difference between the two methods described is essentially that in one the hysteresis of the complex reflectance factor - which is induced by utilising the parametric effect - is modulated by altering the power of an a.c. signal of constant frequency, in the other the modulation of the hysteresis is performed in contrast by altering the frequency of the a.c. signal with constant power.

Title: Method for state control of a synchronous machine having no sensor, in the case of converter supply
Inventor: BECK HANS-PETER DR ING
IPC: H02P25/024
Filed: 1984-06-19
Abstract: In the case of a method for state control of a synchronous machine outside the starting region, the object exists of supplying the invertor on the machine side from a DC source without it being necessary to measure the rotor displacement angle. This is achieved in that the control apparatus for predetermining the invertor control angle  alpha  is synchronised with the stator currents (ISact) of the synchronous machine. The control angle  alpha , which, ignoring the current overlap caused by commutation, corresponds, except for a constant, to the phase-shift angle  phi  between the stator current and voltage ( alpha  =  pi - phi ), is predetermined by a state controller. Said state controller determines a control variable  phi , which is connected to the input of the control apparatus, as a function of the three selected state variables of the system, the "real current", "reactive current" and "capacitor voltage". <IMAGE>

Title: Automatic cereal-inflow regulation for a cereal-cleaning machine
Inventor: RUBERG ALHARD
IPC: B07B11/04
Filed: 1984-08-03
Abstract: Located next to the feed roller (4), Figure 2 and Figure 3 of the drawing, is the so-called feed flap (5), Figure 3, which is loaded by the weight of a lever arm and which has to be opened approximately 20 to 40 mm according to the type of cereal and the power of the machine, so that the cereal can fall in a uniform stream through the vertical sifter onto the screening unit. In a change of cereal, because of the different apparent weight of the individual types of crop, the feed flap has to be reset repeatedly by hand and readjusted during the cleaning process. This is no longer necessary with the automatic mechanism. <IMAGE>

Title: Seat belt system for the occupants of motor vehicles
Inventor: HERBERHOLZ PETER PROF DR ING
IPC: B60R22/19
Filed: 1984-08-07
Abstract: In order to avoid the jolting and sticking effect of seat belts with permanently acting automatic retraction mechanism, which effect is burdensome and has adverse consequences for safety, the retraction force of the belt which is being worn has superimposed on it an opposing force of the same magnitude which is extraneous to the belt system and independent of it, and this force is produced by means of mechanically or electromagnetically produced frictional engagement between a separate clamping device and the belt material and by simultaneous soft-elastic positive engagement between the clamping device and vehicle parts.
